Not all countries have adopted air quality regulations as America has. What impact on human health would these countries experie
nce if they adopt air quality regulations similar to the Americas? The amount of exposure to outdoor and indoor air pollution would remain unchanged. The number of premature deaths related to ultrafine particulate exposure would increase. People would experience a decrease in negative health effects associated with air pollution. Effects from impaired breathing would only decrease for those exposed to outdoor air pollution.
Answer: Long-term health effects from air pollution include heart disease, lung cancer, and respiratory diseases such as emphysema. Air pollution can also cause long-term damage to people's nerves, brain, kidneys, liver, and other organs. Some scientists suspect air pollutants cause birth defects.
